Can anyone help me, im trying to fit a 3.8 bar fpr but unsure of where to fix it and where it actually plums in. Any help or pics etc would be much appreciated.

20vt or 16vt???

You really shouldn't be fitting one without a mapping session immediately afterwards

The car will overfuel by about 25%, causing borewash and engine wear.

its the 20vt, ive just fitted a load of parts together and it will go 4 a map as soon as its bk on the road.

I would strongly recommend that you leave the standard FPR fitted until you get to the place that's doing the mapping, then get them to fit it - its a five minute job

ok m8 will do, any idea who maps them ? i live near cardiff.

i think ive actually bought the wrong fpr anyway. ive bought an fse valve. any suggestions ?

Like I've siad on the other post I haven't got an FPR. I do have a Walbro fuel pump AND I DID GET THE VOLTAGE CHECKED.
